A ttorney Patented Apr. 29, 1930 UNITED STATES PATENT OFFICE EDWIN BIRD WILSON, OF FOREST HILLS, NEW YORK, ASSIGNOR TO DESIGN LABORA- TORIES, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK ELECTRIC LIGHTING FIXTURE Application filed March 18, 1927. Serial No. 176,442.

This invention relates to lighting fixtures of the general type disclosed in my copend mg apphcation Serial No. 25,992, filed April 27, 1925 and relates more particularly to electrio lighting fixtures, such as chandeliers, brackets, etc. constructed from sheet metal or other thin material.

The object of the invention is the provision of a-method for cheaply and easily constructing lighting fixtures from other thin material.

I attain this object by fashioning from sheet metal a plurality of flat elements, cutting notches in the said elements and rigidly interlocking the elements by means of the notches therein. In constructing some forms of fixtures, I find it desirable to provide flexible ears on some of the elements, which may be bent to hold portions of the fixture together.

Other objects and advantages of my invention will be made clear by the following description taken in connection with the accompan 'n 'drawin s. v

In the dr wings, F lg. 1 illustrates in elevation, a lighting fixture constructed in accordance with my invention.

Fig. 11 is a plan view of the fixture shown in Fig. 10.

Figs. 12, 13 and 14 are detail views of the elements makingup the fixture shown in Fig. 10.

Fig. 15 illustrates a boudoir or table lamp constructed according to my invention.

sheet metal or ment 1 on a line with slots 10 and 12 and at right angles to the plane of element 1, engaging the open ends of slots 12 and 21 and sliding the two elements together as far as the slots permit, then springing element 2 into a. bow shape so that the open ends of the two remaining slots, 10 and 20 can be engaged one with the other, and allowing element 2 to resume its natural flat shape, which will cause the elements 1 and 2 to be firmly held against relative longitudinal displacement. Spacer ring 3 is then positioned in slots 11 and 22 by forcing the ring down over the top of the elements 1 and 2 and flexing the said elements slightly to make their width small enough to allow the ring to sli into the slots 11 and 22. When the ring is nally in its proper position as shown in Fig. 1, it serves, by means of slots 24 to hold the ele ments 1 and 2 against relative angular displacement. Stifl'ening element 4 is then interlocked with elements 1 and 2, this being accomplished by sliding elements 4 and 1 together by means of slots 13 and 18, and at the same time bending the bifurcatedend of element 4 downwardly and the notched end of element 2 inwardly so that by slight manipulation the elements 2 and 4 will be rigidly interlocked and held by virtue of slots 19 and 23, thus holding the entire assembly in its proper relation. Ears 14 and 25 of elements 1 and 4 are now passed through slits 26 and 27 in escutcheon plate 5 thus bringing the plate up against shoulders 15 of elements 1 and 4. When the escutcheon plate is 3 y be p siti ed within out out section 16 of elements 1 and 2. The bulb is held by a socket 6 seated in a pocket 17 in elements 1 and 2 and fed by current carried by a wire 8, which passes downwardly and outwardly through holes 9 in the element 4 and escutcheon plate-5 respectively, in such manner as to be hidden from view as completely as possible. The means for holding a bulb socket in pocket 17 is more clearly illustrated and described in connection with Fig. 17

Figs. 7, 8 and 9 show a ceiling fixture comprising three elements 28, 29 and 30 all held together by slots in like manner to the bracket shown in Fig. 1.

Figs. 10, 11, 12, 13 and 14 shown another form of ceiling fixture consisting of four elements 31, 32, 33 and 34. This fixture is assembled in substantially the same manner as the bracket shown in Fig. 1 except that in order to position the spacer ring 34 it is necessary to bend projections 34; of elements 31 and 32, inwardly in order to allow ring 34 to drop past them, after which they are bent back into their original position thus holding the ring 34 in its proper position.

Figs. 15 and 16 show a boudoir or table lamp consisting of two bulb shaped elements 39 and 40 and a heavy base plate 41. These elements are assembled in substantially the same manner as the ceiling fixture shown in Fig. 7

Figs. 17 and 18 show a socket holding arrangement for securing a lamp socket in any one of the forms of lighting fixture which I have illustrated. Reference numeral 49 indicates a square nut which fits tightly in a cut out pocket 48, in the elements 46 and 47, and is retained in the pocket by means of projections 50 of the elements 46 and 47. The

socket is securely attached to the nut 49,

preferably by means of a short screw threaded nipple and is held in proper alignment by additional projections, 51, which frictional- 1y engage the socket under pressure due to the resiliency of the elements 46, 47 and the projections 51.

Fig. 19 shows a socket holding means utilizing a hexagonal nut which would be used in the case of a fixture made of three intersecting elements rather than two.

Fixtures constructed in accordance with my invention can be cheaply, easily, and.

strongly constructed from sheet metal. without the necessity of soldering,nwelding or.

riveting any of the component parts thereof. While such fixtures are extremely light and inexpensive, they give the efi'ect of solidity and massiveness, due to the illusion produced by the intersecting elements. While I have illustrated several fixtures made. of two intersectingelements, it will be found that for best effects in some designs, three or more interesting elements should be used.

It will be obvious to those skilled in the art that the invention is capable of a wide variety of modifications and adaptations and that the present disclosure is intended merely to illustrate its nature without limiting its scope, which is defined in the following claims.

What I claim is:

1. A socket holder for a lighting fixture, consisting of a plurality of plates having a common point of intersection, each of said plates having a pocket cut therein, a nut seated tightly in the common pocket of said plates, a lamp socket secured to the said nutby means of a threaded nipple, means for retaining the nut in its proper position and preventing longitudinal -movement thereof and means attached to the walls of said pocket for supporting the said socket.

2. A lamp fixture consisting of two lates intersecting each other at right ang es, a substantially U- haped opening in each of said plates, a pocket at the bottom of each opening a nut tightly held in the bottom of the pockets, means for preventing longitudinal movement of said nut and a lamp socket secured to said nut by means of a threaded nipple.

3. In a lighting fixture an escutcheon plate, a plurality of profile members having slots therein, said members being interlocked solely by means of said slots, one of said members comprising a light holding portion, and a bracket arm at an angle to and at one end of said light holding portion, a flat member intersecting said bracket arm and cooperating therewith firmly and cooperating with said flat member to hold said profile members in fixed angular relation to one another.

4. In a lighting fixture, a first set of profile members having slots therein and ada ted to interlock with one another solely y means of said slots, one member of said first set of profile members having an angular portion'cooperating and interlocking with an auxiliary profile member to form a second set of profile members, said auxiliary profile member intersecting and interlocking with another member of said first set of profile members, to'hold the component parts of the entire fixture in fixed angular relation to one another.

5. In a lighting fixture, a plurality of profile members, each having a socket receiving opening therein, a first series of notches in the members whereby they may be interlocked and held against lateral displacement, one of said members having an angular extension, an auxiliary member, a main notch in said extension and in said auxiliary member whereby the auxiliary member may be in terlocked with the extension and prevented from lateral movement with respect thereto,

to hold the profile members to the escutcheon plate, a notched perforated member. engaging said profile memberssecondary notches in said auxiliary member at right angles to said main notch, and cooperating notches in one of said profile members at right angles to said. first series of notches, said secondary and cooperating notches servingto interlock the auxiliary member and profile members and hold them against longitudinal displacement.

In testimony whereof, I have signed my i name to this specification this th day of March, 1927.
